HAY ELEVATOR AND CARRIER.

SPECIFICATION forming part of Letters Patent No. 233,633, dated October26, 1880.

Application filed August 27, 1880.

T 0 all whom it may concern Be it known that I, LUCIUS E. MILES, ofFulton, in the county of Rock and State of Wisconsin, have invented anew and useful Improvement in Hay Elevators and Carriers, whichimprovement is fully set forth in the following specification andaccompanying drawlugs.

My invention relates to improvements in hayelevatin g machines forunloading hay into barns or on stacks, by which a car on rollers andoperated by ropes and pulleys is used to elevate and carry the hay toany point desired, said car being suspended under a beam or runway,depositing the hay wherever desired by means of a snatch-rope attachedto a harpoonfork of the usual kind. I attain these objects by themechanism illustrated in the accompanying drawings, in which- Figure 1is a side elevation. Fig. 2 is a perspective view of the car detached.Fig. 3 is a view of the loose pulley and block, Fig. 4 of the hingedgrappling-hooks, and Fig. 5 of the pawl for opening the hooks andholding the car.

Similar letters refer to similarparts throughout the several views.-

The machine may be attached to the ridgepole of a barn or to a beamprovided for the purpose, under which it is suspended by hooks on theunder side of the beam to enter staples in the upper side of the runwayB, said runway-beam being about six inches wide and two and a halfinches thick and any length desired. At each end of said beam arepulleys a a. Staples are set crosswise on the upper side of said beam inrange with said pulleys, so that the draft-rope, passing over thepulleys, will run freely through said staples.

The car 0, Fig. 2, is suspended under the runway-beam by iron straps b1), extending up above the runway, to receive the wheels or rollers 1 23 4 in their upper ends,to carry the car upon the runway-beam, andpassing entirely around under the same. The car is made in two parts,having an open space between the parts, in the center of which islocated a pair of hinged grapplinghooks, Fig. 4, for engaging andholding the loose pulley, Fig. 3. These hinged grappling-hooks arepivoted to crossbars 6 6, extending across the two parts of the car. Onthe forward end of said car is a pul- (ModeL) ley, 01, over which passesthe draft-rope. Said draft-rope is attached firmly to the rear end ofthe car at g, and passes through the loose pulley, and thence up overpulley d in the forward end of the car; thence running along under therunway-beam to its farther end up over pulley a; thence back along theupper side of the runway-beam through the staples to the other end ofsaid runway; thence down over pulley a to a pulley suitably arranged forconnecting the power.

At the rear of the car is attached a weightrope, which passes overpulley f, located near the rear end of the runway on its under side,

to which rope is to be connected a weight to draw the car back to itsoriginal position after the fork is released.

The pawl, Fig. 5, is pivoted at its rear end near the end of therunway,and passes through a rest, 9, located about a quarter of its length fromthe rear end, which rest also serves as a bumper or stop for the car.The forward end of the pawl is wedge-shaped, so that when the car isbrought back to its place the wed ge-shaped point passes between thehinged grapplinghooks, opens them, and releases the pulleyblock whichcarries the fork, so that the latter will descend down to the loadbelow. To insure the opening of both parts of the grapplin ghooks at thesame time, a groove is made longitudinally on the under side of saidpawl from its point, so that the top of the pulleyblock, which issharpened, will slide in said groove and open the grapples each sidealike; also, on the under side of said pawl, at its forward end, it isprovided with a catch, a, which runs over a bar, h, in therear part ofthe car, thus serving as a detent for the purpose of holding the car toits place until afork-load of hay is elevated to it and said car isready for motion.

.When the head of the loose pulley-block is run up and slipped into thegrapples it strikes the under side of the pawl, thus raising it, so thatit is unhooked from the bar h, and the car is then released.

I do not use any particular kind of fork, as any may be attached to theloose pulley, and is independent of the car in its operation, and anyfork may be used which experience proves to be the most suitable.

What I claim, and desire to secure by Letgrappling-hooks attached tosaid car, a de- 10 ters Patent, istachable pulley-block provided with apointed The combination, with beam B, provided head, and suitable draftand weight ropes, subwith pulleys a and pawl-rest g, of a pivotedsrantially as shown and described. pawl attached to said beam, andprovided with a Wedge-shaped or pointed head having a LUOIUS MILESgroove on its under side, the ear 0, adapted to Witnesses: run upon saidbeam,andhavingabar, It, for the ED. 1?.
